Hi Alex, So if you're sending data out there is no or almost no data loss? Have you tried to move the VM to the second host to see if it makes any difference? I actually tried to call you by phone but the call gets dropped once I enter * and your ext. number, as the voice prompt says to. Tried to enter the ext. number directly without *, still without success. Thanks in advance, On Thu, Jun 8, 2017 at 1:59 PM, Герасимов Александр <gerasimov.ay@eksmo.ru> wrote:
Hi Lev.
I am create new virtual host, and run ping from internet.
Ping results 70% packet loss.
But, if i am running ping from virtual host to somebody host in the internet and at the same time, i am pinging this virtual host from internet.
then ping results 0% packet loss or 10% packet loss.

Hi Alex,
That is quite strange...
Does this happen on both hosts - have you tried to migrate the VM to the second host and see if the issue still remains?
Thanks in advance,

NO. both VM's sees two NIC, but on first VM ping with no error, and second VM ping with 75% error.

Hi Alexander,
So if I understand it correctly, you have the following configuration: - 2 hosts, each having 2 NICs - 2 virtual machines, each have a connection to each one of the NICs available on the hosts
On one of the VMs you only see 1 NIC instead of the 2?
Are you sure that the VM is properly configured to have 2 NICs?
What Linux distro and version you're using on the hosts and inside the VMs ?
Can you please send us: - the logs from the VM, e.g. /var/log/messages - the output of lspci -v - the output of ip link
Thanks in advance,

Hi all.
I have to servers with ovirt.
And to identical virtual machines.
Both servers are identical. But on second virtual server not working one network interface. Ping have a problem. I tried to change network driver, but has no effect.
I don't understand that to do
